CAP Barbell · Yoga & Exercise Mats
CAP 1/2-Inch High Density Exercise Yoga Mat with Strap knee pad
Lower concern. Foam yoga mats rarely contain PFAS unless treated.
Exercise mats are typically made from NBR or natural rubber foam without water-resistant coatings. No public evidence of PFAS use in CAP Barbell yoga mats.

What CAP 1/2-Inch High Density Strap knee pad is made of, ingredients and materials
This mat is NBR (nitrile butadiene rubber) foam, a synthetic rubber that is chemically stable and does not off-gas significant volatile organic compounds under normal room-temperature use. NBR is denser and more durable than PVC, making it a common choice for exercise mats because it resists compression and does not require plasticizers like phthalates that soften cheaper alternatives. The polyester strap is a woven fabric with minimal leaching risk at rest. Overall, NBR foam has lower concern compared to other foam-based mat materials.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
VOC off-gassing from foam
NBR foam is relatively stable but may emit minor volatile compounds, especially when new or if heated. Off-gassing risk is low with this material class compared to PVC, but new mats should be aired out for 24-48 hours before use in poorly ventilated rooms.
Coating or surface degradation over time
NBR foam mats may develop surface peeling or flaking with age and heavy use, particularly if exposed to moisture or UV light. Worn surfaces pose a microabrasion risk rather than toxicity, but replacement is recommended if structural breakdown is visible.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Flame retardants
No documentation of flame retardant application to CAP Barbell yoga mats. Yoga mats are not typically required to meet furniture flammability standards, and NBR foam itself is moderately fire-resistant without added chemicals.
Source, EPA ↗Formaldehyde / VOCs
NBR foam does not require formaldehyde-based adhesives in standard manufacturing. The polyester strap may contain trace formaldehyde resins from weaving processes, but this is minimal and not a documented concern for this product line.
Source, ATSDR ↗Heavy metals
Antimony is used as a catalyst in polyester production but typically remains bound in the polymer matrix and does not leach under normal mat use. No testing or recalls for antimony migration from CAP Barbell straps exist in public records.

The brand's record and disclosure
CAP Barbell is a budget fitness equipment manufacturer with no documented recalls or safety controversies specific to yoga mats in public records. The brand does not publish detailed material safety data sheets or third-party certifications (such as Oeko-Tex or GreenGuard) for this product line, which is typical for mid-range equipment manufacturers. No formaldehyde, heavy metal, or flame retardant violations have been established for CAP yoga mats.
How it compares in its category
NBR foam mats sit in the middle tier of safety and durability for yoga/exercise mats. NBR mats show lower concern regarding phthalate content and off-gassing compared to low-cost PVC mats, though they lack the premium certifications of high-end brands using natural rubber or certified NBR with full transparency. CAP's pricing suggests cost-optimized manufacturing, but NBR itself is not inherently problematic, making this a reasonable cost-to-safety trade-off.
If you buy it
Store the mat in a cool, dry place away from direct sunlight and heat sources above 60 degrees Celsius, as foam degradation accelerates with temperature. Rinse with mild soap and water; avoid harsh solvents that can degrade the foam structure. Inspect every 6-12 months for surface cracks, peeling coating, or soft spots. Replace if structural integrity visibly deteriorates, typically after 2-3 years of regular use depending on frequency and care.
